In addition to detailed step-by-step instructions, illustrated explanations of code snippets, and fun, hands-on exercises that lock in learning, the new edition features enhanced coverage of variables, error-handling, and object-oriented programming, as well as fresh data for each chapter’s coding projects, better app deployment, and the latest libraries and tools, such as Plotly, Django, and the Tailwind CSS framework.

As you go from software installation tutorials and language-navigation basics to mastering syntax and troubleshooting, you’ll develop a solid programming foundation for the book’s increasingly complex array of projects. Create responsive 2D games, design your own web apps, and even generate interactive visualisations—all while you pick up and practice clean, universally applicable programming skills!
